EPS batch pre-expander machine (polystyrene expander) machine main features:
1. EPS machine is controlled by PLC full computer touch screen displayer which can realize a full automatic cycle operation of material feeding, steam feeding, temperature controlling, foaming and discharging. And the electronic weighting filling realize quantitative material is exactly and rapidly fed after compressed.
2. The foaming process in the machine is realized in a fully closed stainless steel barrel under constant pressure with high thermal efficiency, economized steam, shortened curing process and high foaming magnification.
3. The machine is composed by famous-brand and high-quality pneumatic elements which can supply a reliable quality and convenient operation to ensure a precise temperature control and uniformity of beading and density.
4. This machine can be matched with sulfurization dryer to realize a continuous operation of drying, screening, breaking and conveying of material for foaming.
5. Vibrating switch control material level to get accurate density, density tolerance less than ±2%.
6. Stainless steel fluidized bed drier keeps inside temperature around 70 ℃.
